This is how Starlight vs. the Witch Doctor goes in My Little Pony: Return of the Witch Doctor.
[Starlight goes to free Twilight]
Twilight Sparkle: Starlight!
Starlight Glimmer: I'll get you out, Twilight.
[As Starlight prepares to free her, the Witch Doctor fires a blast from his Skull Staff and Starlight dodges it. The Witch Doctor chuckles darkly]
Witch Doctor: I should've know you were Twilight's student.
Starlight Glimmer: That's right. Now return the Quaza to the mines, you're gonna kill the Equines.
Witch Doctor: Well that's a risk I'm willing to take.
Starlight Glimmer: Well I'm not.
[She pounces on him and they fight]
[Trixie and Thorax take refuge in a cave and see Twilight pacing]
Trixie Lulamoon: Twilight, what are you doing here?
Twilight Sparkle: I need to help Starlight. I gotta figure out how we can beat the Witch Doctor.
Trixie Lulamoon: Nopony can do it alone. Alright, he's just too powerful.
Thorax: Even Starlight can't beat the Witch Doctor without help.
Trixie Lulamoon: That's right. We're a team.
Twilight Sparkle: Then let's get out there right now and help.
Trixie Lulamoon: Wait just hear me out. We could attack the Witch Doctor together, but he'll be ready for us, he knows our weaknesses. He knows how we fight. Now it's time for us to show him something unexpected, something that he can't beat.
Twilight Sparkle: I'm listening.
[Trixie sees some armor, colored in pink and purple gems. Trixie picks up the armor and gets an idea]
Trixie Lulamoon: Hmm. Okay. These ancient armor pieces are just what we need to create our secret weapon. [to Thorax] Thorax, I'm gonna need your building kit for this. [to Twilight] Twilight, get ready for an upgrade.
[Twilight looks confused]
[The Witch Doctor is still fighting Starlight]
Witch Doctor: You're losing your edge.
[The Witch Doctor is about to attack]
Starlight Glimmer: Maybe it's you who is losing your edge.
Twilight Sparkle: Hey, doc!
[The Witch Doctor turns around to see Trixie, Thorax and Twlight and sees Twilight in Hero Factory Hero armor]
Witch Doctor: Huh?
